My invention relates to improvements in wringers, and the object of myimprovement is to simplify the construction of a clothes wringer,strengthen and cheapen its construction, and lotherwise improve theassemblage of its parts, by shaping its 'frame rigid'- ly as aunitarystructure from metal stamped or formed to produce in one elementa base, side bearing-standards, and front and rear drainage members,with other features of construction auxiliary to the purposes of thewringer.

This object I. have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in which Fig. l is a front elevation of my improved wringer.Fig. 2 is a Itop plan of the unitary frame parts of the Wringer, withother part-s removed,

but showing the lower roll and its bearing blocks emplaced. Fig. 3 is aside elevation of that side standard of the wringer frame which isapertured to pass the projecting end of a roller shaft. Fig. 4 is amedial cross sec- .25 tion of said wringer frame alone taken on thebroken line 4 4 of said Fig. 2.

Minor modifications of the unitary frame structure of this invention arecovered by and are within the scope of the. appended claims.

The frame structure and the hinged closure member 15 of this wringer areconstructed of metal.

The improved frame comprises an upwardly troughed basal part l having amedial depending hollow vent tube 2. This base 'and the other connectedparts of the frame, such as the side hollowr standards 4 and 5 and thefront and rear drainage members 3 are preferably shaped by die-stampingor other appropriate means from a single plate of metal. When sostamped, successiviJ applications of dies are used to shape thedifferent parts of said frame and produce the finished structure, butthese will not be described, being known to and understood by those whoare skilled in the art, but the unitary structure may be made by othermeans, and united from a plurality of different elements.

The basal part 1 has walls 3 projecting to front and rear of thestandards 4 and 5 obliquely outwardly a considerable distance to performthe function of drainage boards. The side Walls of these drainagemembers at 6 are returns to the side standards set oli' inwardly fromthe side Walls of the standards which lat-ter close the sides of thebasal trough 1.

Upper and lower pairs of spaced and apertured ears 11 are punched fromthe outer side wall of the standard 5 to receive fastening bolts tosecure the wringer to any suitable bracketing means, such as agear-case, mounted upon a washing machine or other appliance. Ears 22are partially punched outQalso at 21 from both standards 4 and 5 andbent inwardly in the same horizontal plane to serve assupportingbrackets for the lower sets of bearing-blocksS mountedremovably in the hollows of the standards to receive in longitudinalbearinghollows the end parts of the axial shafts, such as 9, of thesuperposed pair of' coacting elastic rubber rolls 10 and 14.` Thestandards 4 and. 5 are shaped with split inner walls which furnishclearance openings vertically to pass the shaft ends therethrough, andmedially apertured inwardly flanged shield-plates 7 are mounted on theinner margins of these standards and have medial openingsto also passthe shaft ends therethrough. The outer wall of the standard 5 only hasan aperture 13 to pass therethrough the more elongated shaft end 9.

The numeral 15 denotes a pair of like but reversed closure membershaving at their ends depending apertured tongues mounted hingedly uponoutwardly projecting *fixed pins 16 on said standards. These closuresare hollowed inwardly and downwardly to receive the usual bar spring(not shown) whose ends bear compressively upon the tops of the upperbearing blocks 8, the' spring being tensioned by the usual screw 17.

It will be seen, that the frame structure, including the basal trough,standards, and drainage members- 3,'are integral, and with their otherfeatures 22, 6 and '11, are made Ihn Y- i Y. 1,750,835

unitarily, by stamping or otherwise, at la great saving in expense, withmaximum strength.v Having described my invention, what I claim as new,and desire to secure by Letters Patent, is: v 1. nfa wringer, a U-shapedunitary sheet metal frame structure, consisting of like longitudinallyunited halves, thev structure 10 including inwardlyV troughed erectstandards,- and a basal connecting member therefor, being an upwardlytroughed part with upwardly divergent walls wider at the top than saidstandards, the lower parts of said 5 standards having pressed in tonguesto support apertured bearings for roller termina- Y tions, and an endwall of one standard having any aperture to be traversed by one of theroller terminations, said basal member- 2o having a drainage outlet.

2. In a wringer,- a U-shaped unitary sheet metal frame structure,consisting of like longitudinally united halves, the structure includinginwardly trou hed standards, and abasal connecting mem er therefor,being an upwardly troughed part with upwardly divergent walls, the lowerpartsof the standards having inwardly projecting brackets to supportroller-shaft terminations, one standard having outwardly projectingapertured Aears for connections to supporting means, and said basalmember having a drainage outlet.

In testimony whereof I aix my signature.. FLOYD L. CHAMBERLAIN.
